Notes

Added 84g of grapefruit peel (peeled 3 medium ruby grapefruit before starting to measure...lesson learned). See how that goes.

6L sparge, which was the rinse done after removing the mash pipe and completing in a separate bucket, once added to the boil, took it off the boil for 10mins. Still getting my Braumeister routines sorted out. Affected boil-off slightly.
